IMHO, I see that having Intel graphics drivers as an option would be a
welcome addition to the mix of hardware for mythtv. I am definitely in
the "slim/thin frontend client" camp, and for that purpose, I cannot see
the sense in tweaking up the horsepower of my slim/thin frontend clients
to push HD video content when the GPU's I already have can (and should
be able to) do it..
